Abstract

The invention discloses a crustless heat exchanger pipe end air-tightness test device and method, and relates to the field of the heat exchanger manufacturing. Pipe sheets integrated with the pipe bundle are arranged at two ends of the crustless heat exchanger pipe end air-tightness test device; the crustless heat exchanger pipe end air-tightness test device comprises pressing plates and a pressing device; the pressing plate is clung to the upper surface of each pipe sheet by the pressing device; a sealing ring is arranged between the pressing plate and the pipe sheet, and a closed cavity is formed by the pressing plate, a heat exchange pipe and the pipe sheets. The air-tightness test method comprises the following steps: one, preparation before test, and two, air-tightness test. The device disclosed by the invention is convenient for operation, and the method is accurate in leak detection.

Description

technical field [0001] The invention relates to the field of manufacturing heat exchangers, in particular to the field of manufacturing clad heat exchangers without shells, and in particular to a device and method for testing the airtightness of tube ends of heat exchangers without shells. Background technique [0002] Existing general heat exchangers with a shell side are subjected to an air tightness test by injecting gas at the shell side of the heat exchanger and checking for leakage at the tube side. For shell-less wrap-around heat exchangers, such as C-type shell-less wrap-around heat exchangers, this type of product has no shell side, so this method is not suitable for use. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a device and method for testing the airtightness of tube ends of a shell-less heat exchanger. The device is easy to operate, and the method is accurate for leak detection. [0004] ...
